Chemical Structure
Description
3-isopropoxy-4-tributylstannyl-cyclobut-3-ene-1,2-dione (C19H36O3Sn) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-isopropoxy-4-tributylstannyl-cyclobut-3-ene-1,2-dione (CAS 129034-70-4) is a high-purity analytical reference standard with the molecular formula C19H36O3Sn and a molecular weight of 431.20 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-isopropoxy-4-tributylstannyl-cyclobut-3-ene-1,2-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
